notes: Three real documents are served, all on the OAuth/OIDC side of the MCP surface. No security.txt
  (RFC 9116), no api-catalog (RFC 9727), no ai-plugin.json and no A2A agent card on any Dreamdata host.
  The 404 bodies on dreamdata.io and developer.dreamdata.io are the sites' own HTML/JSON 404 pages, not
  SPA soft-200s.

  negative_control: one per host; a 2xx JSON object at an impossible path discards the host
note: 'MCP-host OAuth discovery added 2026-09-19 (roadmap#321/#337): the harvest visits a provider''s
  primary hosts, and RFC 9728 protected-resource metadata lives on the MCP host, so these documents existed
  and were invisible to the scorer. Fetched live and validated on `resource`/`issuer`; one negative control
  per host.'
